TEMPLE THREAD CUTTER FOR LOOMS.

Application filed December 8, 1921. Serial No. 520,883.

To all whom it may concern:

Be it known that I, JONAS Nonrnnor, a citizen of the United States, residing at Hopedale, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Temple Thread Gutters for Looms; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same. v

The present invention relates to an improvement in temple thread cutters for looms. r

The object of the present invention is to re-organize and improve temple thread cutters for the purpose of increasing their efiiciency as cutting implements, reducing the distance of the cut from the selvage, and lowering the cost of the instrument and its maintenance. To the above ends the present invention consists in the temple threadcutter hereinafter described and particularly defined in the claims.

In the accompanying drawings illustrating the preferred form of this invention, Fig. 1 is a side elevation of a temple provided with the thread cutterof the present invention; Fig. 2 is a rear elevation of the same; Fig. 3 is a transverse section of the temple taken on the line 3 4 is a similar section showing the cutter in a different position; and Fig. 5 is a bottom.

lan. The illustrated embodiment of the invention is described as follows: The temple rod is provided with the usual goose-neck 12 which supports the temple proper, having a pod 13 and a cap 14:. The cap is secured to the pod by a screw 15 and a nut 16, fastened through a hole in the ear 17 of .the pod. The cap carries the temple roll '18 which is supported in the cap by means of a screw 19 at the outer end and a screw 20 at the inner end. As seen in'Fig. 1, the boss 21 supporting the inner end-of the temple roll rests upon asurface of the pod. This boss 21 is provided with a tongue 22,

which, as shown in Fig. 1 in dotted lines,

'3, Fig. 5; Fig."

enters an elongated hole or slot 23 in the bottom ofthe pod, adapted'to receive it. The rear end of the boss 21 is bevelled, and

engages a corresponding surface at the end ple roll is of the usual form. Its inner end enters a hole provided in the stationary knife so as'to bring the temple roll close up to the cutting point. The stationary knife 30 is a flat piece of steel provided with one upwardly extended lug 31, and two downwardly extended lugs 32. The upwardly extended lug 31 is received in a flat hole 33 in the cap,.and the two downwardly.

extended lugs 32' are received in two flat holes formed in the pod. -When'the cap is in position on the pod and secured thereto by the screw 15 and nut 16, the stationary knife 30 is securely held in position between the two parts. The movable knife 40 is made of cast iron, and, as shown in Fig. 5, is of substantial proportions. The knife is of substantially uniform-thicknessexcept for the depression in its side, shown at 41,

and except for the heel 42 which is made about twice as thick as the blade of the knife. \Vhen the heel of the knife is struck by the lay, the knife first rollson the fulcrum 13, which engages the back of the goose-neck 12, thereby swinging the knife down into the position shown in Fig. 3, after which further movement of the lay causes the knife to move forwardly, and thereby causes its blade to cut the thread lyingbetween its overhanging hooked end 7 and the edge of the'stationary cutter blade 30. The knife is normally held in raised rearward position by means of the spring 44. The movable knife 40 is pressed against thestationary knife 30 by the knife spring 45, which consists of a piece of steel riveted to the goose-neck by the rivet 46, and having its free end extended rcarwardly alongside of the knife blade. The end of the that the movable 'n'fe spring 25 is roviclecl with rlepres sioh or recess 45, which exienols crazier the screw 20, The spring is hem, shown in Fig, 5, onol th6,hcnt seal of the spring moo molly rests in the recess 4-3 of the lmiie. When, however, the lmiifie is moved forwardly to make its cutting scrolre, its thicker enrl engages the bent portion of the spring, and is thereby pressed sgeinstl the edge of the stationary knife blade to cause it to out the thread. It will he observed that the stationary knife is symmetrical about a vertical axis, and that its vertical edges are beveled slightly (see This is for the purpose of giving it two scissors edges, one of which may be turned around and; put in the other Way, and the other erlge used, thereby cloublin its life. The possage of the movable b ade' over the ed e of the stelionsry blade tends to keep is s 19.1" and besides, the knife may be easily rcmoved and sharpened.

It will he observed that the cap may he removed, and with it comes the stacionary knife blade and temple roll. In such condition the movable blade he removed and replaced, or the temple roll may he removed and. replaced, and the stationary knife may be turned over, sherpenecl, removed or replaced, as may he desired. There is no im- :oeaiiment the removal of the movable kaife at such. time, all that is necessary being to slip the loop on the owl of? spring -13 oil of the car or the log on the side of the knife blade, and pull the knife out of the goose-neck of the. ml. is will also he noted linife blade rloes riot neecl to be sharp in order that is shall be capable of cutting the thread sgeinss the stationary knife blade. The movable knife blade being made of: cast iron is cheap, and setisfacfiory in opemi ion, and if broken or required to be renewed, is easily replaced, The stow t-ionary knife blade is of simple construction, easily shzu'penedmn on oil stone, and. securely and efiici'ent-Iy held. in position when the cap secured to the pocl,
